Time-Out Timer (Tot); Pseudo Trunking; Mic Agc; Radio Registration Service - Hytera PD79X Ex Manual

Time-out Timer (TOT)

The purpose of TOT is to prevent any user from occupying a channel for an extended period. If the preset
time expires, the radio will automatically terminate transmission and keep beeping. To stop beeping,
please release the PTT key. You must wait for a certain time period (preset by your dealer) to initiate
another transmission.
If the pre-alert function is set by your dealer, your radio will alert you to the TOT expiration in advance.
Note: This feature is null in Emergency mode.

Pseudo Trunking

This feature can be enabled via the programming software. If your radio operates on a channel with this
feature enabled and one time slot is already occupied, it can transmit and receive on the other free time
slot, allowing you to communicate timely under emergent situations.

MIC AGC

If enabled via the programming software, your radio will process the audio signals during transmission,
providing improved audio for the receiving radio.

Radio Registration Service

If enabled via the programming software, your radio will automatically register in the system within a
certain period after power-on. Then it can acquire online information of other radios via accessing specific
servers within the valid registration period.

GPS Revert

If enabled via the programming software, your registered radio will transfer its positioning information to
the system when the system requires such information.
